What I learned from this project:

• What are macros and how to use them
• What are the most common predefined macros
• How to include guard your header files

• A header file that defines a macro named SIZE as an abbreviation for the token 1024.

• A header file that defines a macro named PI as an abbreviation for the token 3.14159265359.

• A program that prints the name of the file it was compiled from, followed by a new line.

• A function-like macro ABS(x) that computes the absolute value of a number x.

• A function-like macro SUM(x, y) that computes the sum of the numbers x and y.
